Burning Blank CD-Rs With A NEC DVD burner

I have a NEC DVD-RW NC3540a burner. I'm Using Mac OSX 10.3.9. Now when i go to burn a playlist in iTunes i click on the upper right hand corner, insert a blank CD-R and then click burn. iTunes the starts "Checking Media" for like 30seconds or so and then does nothing. And if i just insert the disk without any programs running Finder won't mount it. What could be the Problem??
